Embodiment
As Fig. 1 and Fig. 2, a kind of inserted-link type speedy recognizer of grain moisture, is made up of an inserted link sensor (1), temperature sensor (2), signal processor (4), AD converter (5), controller (6), LCD displaying block (7), three operating keys (8), accumulators (9); Inserted-link type speedy recognizer of grain moisture is three sections of straight-bar forms, and three sections is inserted link portion, control part and handle respectively; Inserted link sensor (1) is embedded in the cavity foremost in inserted link portion, temperature sensor (2), signal processor (4), AD converter (5), controller (6), LCD displaying block (7) and three operating keys (8) are installed in control part, and accumulator (9) is arranged in the cavity of handle; Inserted link sensor (1) is bi-directionally connected through signal processor (4) with between AD converter (5) and controller (6); Temperature sensor (2) is also through signal processor (4) and is bi-directionally connected between AD converter (5) and controller (6); LCD displaying block (7) and being bi-directionally connected between accumulator (9) and controller (6); Three operating keys (8) are unidirectional is connected to controller (6).
Temperature sensor (2) is for monitoring current environment humidity value, and object records numerical value to inserted link sensing (1) to compensate; Temperature compensation adds negative temperature coefficient semiconductor PN junction device in signalling channel, utilizes the good linear of semiconductor PN within the scope of ± 100 DEG C, passing ratio circuit, realize the auto-compensation of temperature to grain impedance influences.
The rod shaped structure of to be front end be in inserted link portion circular cone, inserted link top is pyramidal structure, is convenient to insert sample.Inserted link sensor (1) is diameter is the cylindric of 10mm, and inserted link sensor (1) has two metal electrodes, and an electrode is arranged in the outer wall in inserted link portion, and another is arranged in the inner chamber in inserted link portion.The electrode be arranged in the inner chamber in inserted link portion is standard signal sender electrode, and what be arranged in the outer wall in inserted link portion is detection signal receiving electrode; Standard signal sender electrode produces a reference voltage value all the time, the signal that detection signal receiving electrode produces is relevant to the humidity of tested grain, therebetween voltage difference can be produced, voltage difference is after the amplification of follow-up signal processor (4), filtering process, be transformed into digital signal through AD converter (5) and enter controller (6) computing, shown by LCD displaying block (7) afterwards.
Signal processor (4) comprises amplifying circuit, current rectifying and wave filtering circuit and weighted circuit three part, the simulating signal that inserted link sensor (1) gathers, first process through current rectifying and wave filtering circuit after amplifying circuit amplification, compare through weighted circuit again, obtain the humidity of tested grain.Weighted circuit is wherein the linearizer of the design according to the non-linear of detection signal, and its core is logarithmic amplifier.What weighted circuit exported is the linear voltage claiming direct ratio with the moisture of detected grain.
Controller (6) adopts model to be the single-chip microcomputer of 80C51, and LCD displaying block adopts LCD1602 type LCD MODULE.80C51 has two 16 bit timing counters, and two interrupt outward, and two timer counters interrupt, and a serial intermit, and have 48 bit parallel input ports.There is clock circuit 80C51 inside, but need quartz crystal and trimmer external.System performance due to 80C51 meets the requirement of system data acquisition and time precision, and the abundant source of product yield is wide, applies also very ripe, therefore is used as control core.LCD1602 type LCD MODULE is a kind of dot matrix type Liquid Crystal Module being used for showing letter, numeral, symbol etc. specially.It is made up of dot character positions such as several 5X7 or 5X11, each dot character position can show a character, has the interval of a some distance between every, often also has interval between row, serve the effect of character pitch and line space, Just because of this so it can not display graphics well.The displaying contents of LCD1602 is 16X2, namely can show two row, often row 16 display character and numeral.
Three operating keys (8) are respectively power switch key, measure key, function setting key; Individual palpation is measured key and is completed single measurement operation; Press function setting key and can carry out cyclic switching between several difference in functionality, simultaneously by the value measuring key change corresponding function item.For avoiding grain variety factor and quality factor to affect, instrument should select different measuring basis values to different grain varieties.Therefore, first instrument carries out reference value adjustment before measuring.
As Fig. 3, a kind of specific implementation process of inserted-link type speedy recognizer of grain moisture is:
After start, first system carries out self-inspection and initialization, carries out system initial value selection and setting according to different types of food; If system power supply electricity is not enough, there will be the alarm of hummer.
Inserted link portion is inserted in tested grain heap or bag, and press measurement key, when being greater than 1s upon pressing the key, start measurement data once, repeat to insert in grain heap or bag in different orientation to press and measure key and measure; After gathering for 5 times, singlechip controller just can calculate this mean value measured, and compares with the preset value in system, and the result of detection is shown in LCD display, can read intuitively.When the grain moisture recorded is above standard limit value, system can carry out warning reminding.
